Value-Based Care and Its Impact on Care Management

Value-based care (VBC) is a payment and delivery framework in which providers are reimbursed based on patient health outcomes rather than the volume of services rendered. This page covers the structural definition of value-based care, its operational mechanics, the care management scenarios it shapes, and the boundaries where VBC obligations begin and end. Understanding this framework is essential for care managers, health systems, and payers operating under federal quality programs administered by the Centers for Medicare & Medicaid Services (CMS).

Definition and Scope

Value-based care restructures the financial relationship between payers and providers by tying reimbursement to measurable quality indicators, cost efficiency, and patient outcomes. The framework contrasts directly with fee-for-service (FFS) models, in which payment is triggered by each discrete billable encounter regardless of clinical result.

CMS administers the primary federal value-based programs through the Center for Medicare and Medicaid Innovation (CMMI), established under Section 3021 of the Affordable Care Act (42 U.S.C. § 18041). CMMI has tested over 50 payment models since its 2010 authorization, spanning primary care transformation, specialty care bundling, and population-based accountability.

VBC encompasses four broad model types, classified by CMS according to the level of financial risk assumed:

1. Pay-for-Performance (P4P): Bonuses or penalties tied to performance thresholds on quality metrics; providers retain FFS base payments.
2. Shared Savings: Providers share a portion of net savings against a spending benchmark when quality standards are met (e.g., Medicare Shared Savings Program, or MSSP).
3. Bundled Payments: A fixed payment covers all services within a defined episode of care (e.g., 90-day joint replacement episode under the Bundled Payments for Care Improvement Advanced, or BPCI Advanced, model).
4. Global Capitation: A per-member-per-month (PMPM) payment covers a defined population's total care; the provider assumes full upside and downside risk.

The scope of VBC obligations touches care management models and frameworks directly, because outcome-linked reimbursement makes structured care coordination a financial as well as clinical imperative.

How It Works

Under VBC contracts, participating providers are measured against benchmarks derived from historical cost data, regional averages, or national quality standards. CMS uses the Merit-based Incentive Payment System (MIPS) and Alternative Payment Models (APMs) as the two tracks under the Quality Payment Program (QPP), established by the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA, Pub. L. 114-10).

The operational sequence for a typical shared savings arrangement follows discrete phases:

1. Attribution: Patients are assigned to a provider or care team based on plurality of primary care visits during a baseline period.
2. Benchmark Setting: A spending target is established using attributed patients' historical expenditures, adjusted for risk using CMS Hierarchical Condition Categories (HCC) scores.
3. Performance Period: The provider delivers care across a 12-month performance year; total expenditures and quality scores are tracked.
4. Reconciliation: At year-end, actual spending is compared against the benchmark. Savings or losses are calculated; quality scores determine the share of savings returned or the magnitude of penalties applied.
5. Quality Reporting: Providers submit data on measures drawn from the CMS Web Interface, CAHPS surveys, or electronic clinical quality measures (eCQMs).

Risk stratification in care management is structurally embedded in this sequence: HCC coding accuracy directly determines the benchmark, meaning undercoded patients lower the benchmark and increase financial exposure for the provider organization.

Population health management tools and care management quality metrics are the primary operational instruments providers use to perform within these contracts.

Common Scenarios

Value-based care obligations manifest differently depending on the model type and the patient population involved.

Accountable Care Organizations (ACOs): Under the MSSP, ACOs are groups of physicians, hospitals, and other providers who share accountability for Medicare beneficiary outcomes. As of the 2023 program year, CMS reported 480 active MSSP ACOs covering approximately 10.8 million assigned beneficiaries (CMS MSSP Fast Facts, 2023). ACO care managers coordinate high-risk patient panels, closing care gaps and reducing avoidable admissions.

Bundled Payment Episodes: Orthopedic, cardiac, and oncology specialties operate under episode-based contracts. The oncology care management function is particularly affected by the Oncology Care Model (OCM) and its successor, the Enhancing Oncology Model (EOM), which requires participating practices to provide enhanced services including 24/7 care management access and a care plan aligned with the Institute of Medicine's domains.

Chronic Disease Management: Patients with diabetes, heart failure, or COPD generate the highest per-capita costs under FFS and represent the highest-priority cohort in VBC. Chronic disease care management protocols — including medication reconciliation, self-management education, and transition follow-up — directly reduce readmission rates that trigger quality penalties under the Hospital Readmissions Reduction Program (HRRP) (42 C.F.R. § 412.154).

Medicaid Managed Care Value-Based Arrangements: States contracting with managed care organizations (MCOs) under Medicaid may require VBC pass-through arrangements to providers, governed by federal managed care regulations at 42 C.F.R. Part 438, as amended effective February 25, 2026. Covered entities must ensure that internal policies, documentation standards, and audit protocols reflect the current amended regulatory text rather than superseded provisions. Survey and enforcement activity by CMS and State Survey Agencies will be measured against the amended standard as of the February 25, 2026 compliance date; reliance on prior regulatory text is not a permissible basis for avoiding deficiency citations under the updated rule.

Decision Boundaries

VBC frameworks have defined structural limits that determine where accountability begins and ends.

Model vs. Program Participation: Participation in a CMMI model (e.g., BPCI Advanced) is voluntary for most provider types; participation in MIPS under QPP is mandatory for clinicians billing above the low-volume threshold ($90,000 in Medicare Part B charges or 200 Medicare patients annually, per CMS QPP participation criteria). The distinction governs the degree of financial risk assumed.

Attribution Boundaries: A patient attributed to one ACO cannot simultaneously generate shared savings credit for another. CMS attribution rules use a two-step process: first assigning patients with primary care evaluation and management (E&M) visits, then assigning remaining patients based on plurality of services. Unattributed patients fall outside VBC accountability regardless of clinical need.

Quality Measure Applicability: Not all quality measures apply to all model types. MIPS Value Pathways (MVPs), phased in beginning with the 2023 performance year, organize measures into specialty-relevant clusters, replacing the prior all-or-nothing measure selection approach. Providers in Advanced APMs with sufficient Medicare revenue participation are exempt from MIPS reporting requirements.

Care Management Service Billing Under VBC: Chronic Care Management (CCM) codes (CPT 99490, 99491, 99487, 99489) and Transitional Care Management (TCM) codes (CPT 99495, 99496) remain billable under FFS and coexist within VBC arrangements. Care management reimbursement and billing rules establish that these codes cannot be billed during the same service period as certain CMMI model payments that cover the same functions — a boundary that requires coordination between billing compliance and care management operations.

Social Determinants and Non-Clinical Factors: VBC models hold providers accountable for outcomes partly driven by factors outside the clinical encounter. Social determinants of health in care management — including housing instability, food insecurity, and transportation barriers — affect readmission and adherence rates measured under VBC contracts, but no federal VBC model currently adjusts benchmarks for social risk factors in a fully standardized way, creating documented equity concerns raised by the National Academy for State Health Policy and the Medicare Payment Advisory Commission (MedPAC) in its March 2022 Report to Congress.
